Problems solved by technology

[0004] However, this method often only arranges the explosive on the surface of the area to be detonated and detonates it. The explosive can only be blasted on the surface of the area to be detonated. If the detonated area is an ice layer with a certain thickness, the effect of blasting only on the surface is not ideal. , therefore, we propose a pre-buried blasting device and its application method

Embodiment 1

[0031] Such as figure 1 As shown, this embodiment provides a pre-buried blasting device including a plurality of conical blasting heads 2 for screwing into the area to be detonated, a mounting plate 1 and a motor, the motor is connected to the mounting plate in transmission, and the motor will be able to Drive the mounting plate to rotate. The conical casing of the conical blasting head is made of hard alloy, which facilitates the screwing of the conical blasting head into the area to be detonated.

[0032] Such as figure 2 As shown, the pre-buried blasting device also includes a base 6, on which a motor mounting base 71 and a mounting plate support base 8 are arranged, the motor 7 can be mounted on the motor mounting base, and the mounting plate supports The seat support is located under the mounting plate, and the mounting plate can be installed on the mounting plate support seat through an arc-shaped rotating bearing, so that during the operation of the motor, the transm...

Embodiment 2

[0045] On the basis of Embodiment 1, the conical shell of this embodiment is formed by matching and connecting two semi-conical shells. The opposite sides of the two semi-conical shells are respectively provided with concave grooves and raised parts. The starting parts match, and the two semi-conical shells can be mated and connected. The outside of the semi-conical shell is also provided with two belt mounting holes 501 (such as Figure 5 As shown) the installation part 5 (when the two semi-conical shells are closed, the installation part and the through hole are staggeredly distributed on the closed conical shell), the two installation parts are symmetrically distributed on the semi-conical shell, Bolts pass through the mounting holes of the two semi-conical shells, and then the two semi-conical shells are fixedly connected by nuts.

[0046] The semi-conical shell includes a tapered part and a mounting end, the rear end of the tapered part is integrally connected with the m...

Embodiment 4

[0048] On the basis of any one of embodiments 1-3, a plurality of fourth connecting rods and a plurality of fifth connecting rods are also arranged on the mounting plate in this embodiment (the second connecting rod, the first connecting rod can also be arranged according to the needs). The arrangement rules of the three connecting rods, the fourth connecting rod and the fifth connecting rod, and then arranging multiple sixth connecting rods or multiple seventh connecting rods, etc., the following only uses the fourth connecting rod and the fifth connecting rod for illustration), A plurality of fourth connecting rods and a plurality of fifth connecting rods are all circumferentially arranged outside the first connecting rods, a plurality of second connecting rods, a plurality of third connecting rods, a plurality of fourth connecting rods and a plurality of fifth connecting rods The radius of the circle formed by the connecting rods increases gradually, and the lengths of the f...

Abstract

The invention belongs to the technical field of blasting, and discloses an embedded-type blasting device. The embedded-type blasting device comprises a plurality of conical blasting heads for screwinginto an area to be detonated, a mounting plate and a motor, wherein the conical blasting heads comprise conical shells, detonators, emulsion explosive and detonating cords, and thread grooves are formed in the conical shells concavely in the rotation direction of the conical shells; the mounting plate is provided with a first connecting rod, a plurality of second connecting rods and a plurality of third connecting rods, wherein the first connecting rod, all the second connecting rods and all the third connecting rods are detachably connected with one conical blasting head in a matched mode correspondingly, and the lengths of the first connecting rod, the second connecting rods and the third connecting rods are reduced progressively; and a motor is in transmission connection with the mounting plate. The invention further discloses a using method of the embedded-type blasting device. As all the conical blasting heads are conically distributed in the area to be detonated, blasting can becarried out in the area to be detonated, the blasting effect is better, and the working efficiency is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of blasting, and in particular relates to a pre-buried blasting device and a using method thereof. Background technique [0002] In large-scale projects such as railways, mines, and reservoirs, the role of blasting technology is very important. Blasting technology is used in mining and road construction, digging tunnels, and demolishing old buildings in cities. With the development of economy and the increase of engineering construction, blasting has attracted more attention. [0003] As a science and technology, blasting is widely used, but it is undoubtedly the most important and common application in engineering. Mining and mountain opening, railway and road repairing use drilling and blasting to excavate tunnels, and water conservancy projects are also used in some cities. Also used to demolish buildings. Use the huge energy generated by the explosion of explosives to destroy the original structure of...
